Start: Stand tall with your feet shoulder-width apart. Hold a dumbbell in each hand with an overhand grip. Bring each dumbbell up so that they’re alongside your shoulders. Your palms should face forward. Engage your abs.

Movement: Push one hand straight up overhead until your arm is fully extended. Pause for a moment, and then lower it back down. Repeat with your other arm to complete 1 rep. Continue to alternate sides, pressing each arm up and then lowering it back down, for the designated number of reps.
